2. Description of the Prior Art

As segments of the population, such as the “baby boomer” generation, getolder, the market for products that help reduce the signs of aging hasdrastically increased. One of the major areas of concern for many peopleis the reduction of wrinkles in facial skin. Many different types offacial creams have been developed over the years that claim to reducewrinkling of the skin, but people have still sought better ways ofaddressing the problem. One of the newer approaches even includesinjecting a form of botulism under the skin to smooth out wrinkles.However, people still seek new products that provide improved resultswith as little cost, time and pain involved as possible.

There also have been several different devices developed to address theproblem of reducing wrinkles in the skin. The following briefdescriptions of previously issued United States Patents provide arepresentation of the devices in the prior art that have been created toaddress the problem of reducing wrinkles in the skin.

U.S. Pat. No. 6,443,915 issued to Hwang discloses a control method anddevice of a portable beautifying apparatus. The method and device usegalvanic ion current, far infrared ray, and vibration to beautify thehuman skin.

While some of these devices discussed may provide a certain amount ofnoticeable results in reduction of wrinkles of the skin, there stillremains a need for a non-invasive apparatus that produces improvedwrinkle reduction in the skin. To answer this need, the claimedinvention provides a method for aesthetic skin treatments.

SUMMARY OF THE INVENTION

To satisfy the need for an apparatus that reduces the appearance ofwrinkles in the skin, the claimed invention provides a method foraesthetic skin treatments. It has been previously known that placingLEDs emitting light of differing wavelengths adjacent the skin of asubject can provide beneficial results to the subject. However, varyingthe wavelength of the light alone and maintaining other characteristicsof the light emitted by the LEDs unchanged produces minimal results. Thewavelengths of the LEDs employed in the claimed invention are used ascarriers to transfer modulation of the emitting frequency and poweroutput of the LEDs to provide an aesthetic skin treatment to the skin.

A primary object of the claimed invention is to provide a new method foraesthetic skin treatments that provides improved results over previousdevices.

Another object of the claimed invention is to provide a new method ofaesthetically treating the skin that does not require a medicalprofessional to perform the method.

A further object of the claimed invention is to provide an apparatusthat modulates the emitting frequency of an electrical light sourceduring an aesthetic skin treatment.

The massage control 70 allows an operator to activate a vibrationmeans within the large pulsator to provide a massaging action to thesubject's skin when the large pulsator is being used.

The small pulsator has a single 625 nm wavelength LED at 40 mW centrallylocated at the tip that is powered by a power supply cord removablyconnected to the control console. The small pulsator is used inapplications where the area of skin that is targeted for aesthetic skintreatment is small. The tip of the small pulsator is preferably coveredwith a sanitary cover.

The large pulsator and vibration means are supplied power by a powersupply cord that is removably connected to the control console. Thelarge pulsator has a head with 12 radially spaced 940 nm wavelength LEDsat 20 mW about the head and a 625 nm wavelength LED at 160 mW is locatedat the center of the head. The large pulsator is used in applicationwhere a general area of skin is targeted for aesthetic skin treatment.The head of the large pulsator is preferably covered with a sanitarycover.

The circuitry within the control console provides a frequency modulatingmeans and a power output modulating means that control the emittingfrequency and power output of the LEDs within the large pulsator andsmall pulsator.

Each control has an LED adjacent thecontrol that provides a visual indication as to the status of theparticular control. The control console 20 may optionally have a unitlock key switch (not shown) to prevent unauthorized use of the apparatus10. FIG. 8 shows a block diagram of the circuitry 135 that is containedwithin the control console housing 140 and is controlled by amicrocontroller 150. Power is supplied to the circuitry 135 asunregulated 12 volts DC derived from either a battery or from aconventional unregulated AC/DC power supply.

The session timer has a two digit LED timer display 50 controlled by twotimer select controls 60 that are provided for an operator to set thenumber of minutes that a particular session will last. An audible alarm160 is also provided that can be programmed to notify the operator of apredetermined time interval, signaling that the operator shouldreposition the pulsator to a different portion of the skin targeted foraesthetic treatment to assist the operator in applying an even aestheticskin treatment to a subject. Preferably, the audible alarm is programmedto beep every 10 seconds during use of the large pulsator and every 18seconds during the use of the small pulsator. However, themicrocontroller can be programmed to allow an operator of the apparatus10 to change the audible alarm time intervals to meet particular needs.FIG. 8 shows how the session timer 50 and audible alarm 160 areconnected in the circuitry 135 contained within the control consolehousing 140.

The massage control 70 allows an operator to selectively activate avibration means 170 within the large pulsator 30 to provide a massagingaction to the subject's skin when the large pulsator 30 is being used.FIG. 8 shows how the massage control 70 is connected in the circuitry135 contained within the control console housing 140 and to thevibration means 170 in the large pulsator 30.

The small pulsator 40 shown in FIGS. 4 and 7 is controlled by the smallpulsator control 80 that allows an operator to selectively activate thesmall pulsator 40 for use during a session. The small pulsator 40 has asingle 625 nm wavelength LED at 40 mW 180 centrally located at the tip190 that is powered by a power supply cord 195 removably connected tothe control console 20 as shown in FIG. 1. The circuitry 135 within thecontrol console housing 140 provides a calibration driver 200 that workswith a calibration resistor 210 within the small pulsator 40 tocalibrate the output of the small pulsator 40 to compensate forvariation in LEDs used in the small pulsator 40 from unit to unit toensure consistent operation of the apparatus 10. FIG. 8 shows how thesmall pulsator 40, small pulsator control 80 and calibration driver 200are connected in the circuitry 135 contained within the control consolehousing 140.

The pause control 90 allows an operator to selectively temporarily pausea session, stopping the session timer 50 and turning off the largepulsator 30 and small pulsator 40. FIG. 8 shows how the pause control 90is connected in the circuitry 135 contained within the control consolehousing 140.

The large pulsator 30 shown in FIGS. 2 and 6 is controlled by the largepulsator control 100 that allows an operator to selectively activate thelarge pulsator 30 for use during a session. The large pulsator 30 andvibration means 170 are supplied power by a power supply cord 220 thatis removably connected to the control console 20 as shown in FIG. 1.FIG. 3 shows that the large pulsator 30 has a head 230 with 12 radiallyspaced 940 nm wavelength LEDs at 20 mW 240 about the head and a 625 nmwavelength LED at 160 mW 250 is located at the center of the head 230.The head is designed as a heat sink to dissipate heat away from the LEDs240 and 250. The large pulsator 30 employs culminating and diffusinglens 255 with the center LED 250 to direct the light emitted from thecenter LED 250. The circuitry 135 within the control console housing 140provides a calibration driver 260 that works with a calibration resistor270 within the large pulsator 30 to calibrate the output of the largepulsator 30 to compensate for variation in LEDs used in the largepulsator 30 from unit to unit to ensure consistent operation of theapparatus 10. FIG. 8 shows how the large pulsator 30, large pulsatorcontrol 100 and calibration driver 260 are connected in the circuitry135 contained within the control console housing 140.

The circuitry 135 within the control console housing 140 provides afrequency modulating means and a power output modulating means thatcontrol the emitting frequency and power output of the LEDs within thelarge pulsator 30 and small pulsator 40. The Phase controls 110-130modulate the emitting frequency of the LEDs in the small pulsator 40 andlarge pulsator 30 for different time intervals at the followingfrequencies: Phase I 73 Hertz for 1 second, 292 Hertz for 1 second, and584 Hertz for one second. Phase II 73 Hertz for 2 seconds, and 584 Hertzfor 1 second. Phase III 73 Hertz for 4 seconds, and 584 Hertz for 1second.

The Phase controls 110-130 also modulate the power output of the LEDs inthe large pulsator 30 and small pulsator 40 to the following radiantlight levels at the surface of the skin: Large Pulsator Small PulsatorPhase I 60 mW/cm² 6 mW/cm² Phase II 70 mW/cm² 7 mW/cm² Phase III 80mW/cm² 8 mW/cm²

The apparatus 10 is used by first switching on the power switch to theapparatus 10. When power is initially provided to the apparatus 10, themicrocontroller 150 sets the apparatus 10 to Pause mode, the phasecontrols to phase I operation, the massage control 70 to off, and resetsthe session timer 50 to zero minutes. An operator then sets the variouscontrols on the control console 20 to their desired settings in order tocomplete an aesthetic skin treatment session by first setting thesession timer 50 to a desired session time interval. Next, the operatorwill select the phase control 110-130 desired for the particularsession. The Phase controls can be changed at any time during a sessionby pressing the appropriate control. The associated LED indicator willilluminate reflecting the phase status within the microcontroller 150with only one of the LED indicators being illuminated at a time. Duringoperation of the apparatus 10, the microcontroller 150 continuouslycycles through the emitting frequencies based upon the phase controlselection.

The operator then selects the desired pulsator control 80, 100 for theparticular session. If the large pulsator 30 is selected for a session,the operator has the option of selecting the massage control 70 toactivate the vibration means 170 within the large pulsator 30. Wheneither the large pulsator or the small pulsator is selected, the pauseLED will go out indicating that the pause control has been deactivated.

The small pulsator 40 is used as shown in FIG. 7 in applications wherethe area of skin that is targeted for aesthetic skin treatment is small.The tip 190 of the small pulsator 40 is preferably covered with asanitary cover 280 as shown in FIGS. 4 and 7 made of translucent plasticthat is disposed of after each treatment. The 625 nm wavelength of theLED is used as a carrier to deliver the modulated emitting frequency andpower output of the LED created by the frequency modulating means andthe power output modulating means. The modulation of the emittingfrequency and the power output of the LED works together to produce anaesthetic skin treatment when the small pulsator 40 is placed adjacent awrinkle in the skin of a subject.

The large pulsator 30 is used as shown in FIG. 6 in applications where ageneral area of skin is targeted for aesthetic skin treatment. The head230 of the large pulsator 30 is preferably covered with a sanitary cover290 as shown in FIGS. 2 and 6 made of translucent plastic that isdisposed of after each treatment. The 940 nm wavelength of the radiallyspaced LEDs and the 625 nm wavelength of the centrally located LED areused as carriers to deliver the modulated emitting frequency an poweroutput of the LEDs created by the frequency modulating means and thepower output modulating means. The modulation of the emitting frequencyand power output of the LEDs work together to produce an aesthetic skintreatment when the large pulsator 30 is placed adjacent a wrinkle in theskin of a subject.
